WEATHERTBOOF'RAILSTAND FOR TRACK SCALES.

Application ined May 1,

To all 11i/@0m` 'it may conm/m.'

Be itv known that I, JoHN VIIsoN Gir noon", citizen of the Dominion ofCanada, residing at Montreal, in the Province of Quebec and Dominion ofCanada, have in=r vented certain new andV useful Improvements inVVeathei-proof Raill Stands for Track Scales, of which the following"isa specification.

This invention relates to improvements in weather covers for trackscales, and more particularly to an improved stand for supporting therails and Ventilating the scale pit While prevent-ing the ingress ofWater.

The freezing of drain water or water of condensation on the workingparts ofthe scalo mechanism is objectionable to the proper maintenanceof track scales; There fore, it is desirable to keep Waterffronidraininginto the pitA as Well as to provide the proper circulation of airtocarry off moisture and to that end the constructions shown inmy priorpatents, 1,335,599, March 30, 1920, and 1,426,003, August 15,1922, weredesigned. In the construction of the former patent, the dead railsaresupported directly on the deck of the pit', While the live rails aresupported on the scale Within the pit through the mediumr of rail standswhich proj ect through openings inthe deck. In thelatter patent the deadrails are supported on rail stands which project through theopenings in:the deck, thev rail stands being in turn mountedfon a solid sup-portindependent of the deck, While the live rails are supported on the scaleina manner similar to that disclosed in the former patent. In eachconstruction, :the rail stands which project through the openings in thedeck are each provided with a depending; apron whichl overhangs aflashing secured tonthe deck, thus permitting the ventilation of theypit and at the same time preventing` the ringress of Water. The standand the integralil apron above noted are formed of cast metal andconsequently this construction prevents ready access for the insertionor manipula tion of the rail clamping bolts. The clamp-y ing means forthe rails include clamping plates and bolts, the latter because of saidinaccessibility, being passed upwardly through theA head of the railstand. This necessitates the locking nut being associated withl theupper end ofthe holt` and conse" 1923. Serial No. 635,962.

quently this nut is exposed to the atmosphere which results inthe'corrosion of the parts.v It is. impracticable lwith this type toreverse the bolt so as to protect the nut.

froml the weather becausefthe integral del to permit ready access to thelocking nut of the I rail.v clamping means.

Another objectfof the invention is to provide a detachable apron whichisadapted to be liftedy vertically into position, and then rotatedhorizontally into interlocking engagement with` the head of the railstand, whereby the apron `will be held against vertical movement.

A further objectv of theinvention is toprovide such an apron with meanscooperating with the rail` stand'head to` preventlateral creeping of theapron and consequent displacement thereof.

A still further object ofthe invention is to provide an apron and also aflashing of sheet metal:r which will be cheaper to manufacture thanthe-aprons and lashings heretofore employed.

Other objects of to those skilled in this art as thedetails of" thisimprovement are more fully described,- illustratedand claimed, andthough the es sential features of theiinprovement are necessarilysusceptible oi avvide range of structural modification,r a. preferredand practical embodiment is shown in the accompanying drawings, in whichn Figure l isa staggered longitudinal sectionalA view showing themounting of both the live and dead rail stands independently of the roofand the means for supporting the latter.

Figure 2 is a detail showing in cross-seoY tion the supports for boththe live and dead rails, and also showing my improved apron andflashing.

'ure 5 is a top plan 'iiew ot one ot the s. deta l sectional. view show-'tor ,lock Y he apron against l creeping. a perspectiye view ol the 8 isa perspectii'e view of the I no' out the in'=.'ention`r I provide theusual scale pit 5 and eo'fer the sante by my arched deck (S. sueln 'torinstance. is shown my prior patent No. 1,4QG`0O3. rllhe decli ifsupported independently ot the lire rails T and dead rails S hy meansoit a series oi? beams E). The dead rails are solidly supported on a pitstructure throun'h the medium of an I-beain 10, and the live rails aresupported on the scale (not shown) threujgjh the medium of metalsupports 11. lloth the I-beam or support 10 'tor the dead rails, and thesupports 11 'tor the lire rails are disposed below the deck, and inorder to support both the live rails and the dead rails in an elei" pposition above the deck and in such rY as to permit et the de'rkdraining` the w outwardly to the sides and ends ot' the scale pit, Ihave provided a plurality ot rail stands 12 and 13 for the respectivelire and dead rails. rlhese stands project upwardly through openings1dr- Vformed in the deck. Inasmueh as the rail stands and the associatedapron and llashina' are identical, the description ot one will sultiee.

Each rail stand is preferably formed of cast metal, and includes acircular base 15 and circular head 1G the latter being concentric withthe base, but having a considerably greater diameter. The diameter otthe base 15 is considerably less taan the diameter ol the opening' l-lso as to provide a resultant air passae'e 1'?. The diameter ot the head1li is e're laan the ojuenina' 1f-il so to overlap the s thereof.Connectingthe head and be a plurality oll vertically disposed radial ris 18. In the construction shown there are lour ol" these ribs arranfredequi-distant apart. rlhe base provided with suitable openings tor theinsertion oll attaching' bolts whereby the i'ail stand may be secured toeither a beam 10 or to a support 11.

rllhe i'ail is seated upon the head 16 and is secured thereto by theclamping` plates or clips 1S). bolts 2() passing' downwardly throughaligned openings 21 and 22 respectively 'termed in the plates 19 and theheads 1n. @n the lower end ot each bolt is threaded a locking' nut saidnut bearing' against the under 'tace ot the head 1G. The

bolt opening:- are dispose( in close. proximity to the outer edges oitthe ribs 1S, whereby the nuts 23 will ene e'c said ribs and thus beprevented troni turning. Each bolt is formed with an angular head whichmay be eiuagcd by a tool t'or the purpose of turning' the bolt. Byj'rrojecting' the bolt downwardly and positioning' the nut on theunderside ol' the head 1G, said nut and its threaded connection with thebolt is protected 'trom the weather and consequently corrosion ot theparts is aroided.

In order to permit the pit being properly ventilated through the.passage 17 and at the same time prevent the ingre *t water into the pitthrough said passage, I have provided a` flashing 2l; and an apron 95which are arranged in telescopic relation and are respectively carriedby the deck (3 and the head 1G ot' the rail stand.

The flashingl 94- is VFormed lrom a strip ol fi sheet metal and bentinto circular torniation, the meeting ends being' interlocl-:ed asindicated at -il The internal diameter ot the llashing' is substantiallyequal to the diameter of the com'espondinler openinj r 14 d in the deck.The lower edge portion ot the flashing is cut into a plurality ofattaching sections 26 these tions being subsequently bent outwardly atright angles to form an attaching' tlang'e. Each section ot this f'tlange is formed with an opening' Q7. The tlashingr is seated upon theplankingr ot the deck (3 and is disposed in alignment with thecorresponding openingr 1l. Nails are then driven through the openings 17ot the tlairn'e 2M sections Q6 and into the deck planking so as torigidly secure the flashing against movement. The weather-prooling'material (5 ot' the deck is then lapped over the l'lange sections 26 soas to create a water proof joint.

The apron 25 likewise formed trom a single stip ot sheet metal and isbent into circular formation, the meeting ends being interlocked as at'25- T he diameter ot the apron is not only greater than the diameter otthe flashing' l, but greater than the opening; 1l, thus providing' anair passage 2S between the llashinpl and the apron. The upper edge ol"the apron 25 is adapted to be positioned in a downwardly extenl'linerperipheral recess 29 'termed in the head 1h ot the rail stand. In orderto support the apron against vertical movement7 I have provided the head16 ol thc rail stand adjacent the periphery thereof with a pair ot'diametrieally opposed depeiulinpr .lugs 23d-23u which are respectivelyVformed with inwardly extending' slots or seats .'-ll tor receivinginwardly extending' lues E2-32 stamped trom the body ot' the apron. Inorder to i'i' prevent lateral creeping' ol the. apron and consequentdisphu'ement thereof.I due to the passage ot ears along the rails. Ihave provided the apron with an inwardly extendini.r

maaien of openingsy 34.' The lng 33 yis adapted'to be disposed' directlyagainstthe-lower suny face of the head 16' and a locking pin- 35 ispassed through an openingy in the head and intol any one of the openings-34'of said lug 33.

From the foregoing,

sides thereof; that the flashing and the apron serve to prevent theingress of water into the scale pit andat the sameftime permit the" ingmeans have been properly positioned andsecured the apron may be easilyraised so that its upper edge will be disposed within the peripheralseat 29 of the head, the apron being then turned in a horizontal planeand interlocked with said head, after which the locking pin 35 will beseated to secure the apronagainst any lateral movement due to creepingcaused by the passage of cars along the rails. It will also be observedthat by means of the detachable connection between the apron and thehead, I have provided means whereby ready access may be had to the railfastening means either in assembling or in repairing the structure.
